Bug report: product over x not being parsed correctly

I'd like to report another MathML bug I'm afraid. I have a document with
a product over x (i.e. upper case pi, subscript x). When I open the
document I get a parsing error ("Some tag/attributes are ignored") and
the upper case pi is shown as "&PI;".

I have tried deleting the product symbol and putting in a new one. But
when I reload the document after doing this, I get the same problem.

Here's the HTML:
<p>Number of typical strings &sim; <math
xmlns="http://www.w3.org/1998/Math/MathML">
  <mfrac>
    <mrow>
      <mi>n</mi>
      <mo>!</mo>
    </mrow>
    <mrow>
      <munder>
        <mo>&PI;</mo>
        <mi>x</mi>
      </munder>
      <mo>(</mo>
      <mi>np</mi>
      <mo>(</mo>
      <mi>x</mi>
      <mo>)</mo>
      <mo>)</mo>
      <mo>!</mo>
    </mrow>
  </mfrac>
  <mo>&ap;</mo>
  <msup>
    <mn>2</mn>
    <mrow>
      <mo>+</mo>
      <mi>nH</mi>
      <mo>(</mo>
      <mi>x</mi>
      <mo>)</mo>
    </mrow>
  </msup>
</math>
</p>

Thanks,
Joe
